I am not sure this is the best way, but you can run yourself again:

BEGIN{
    unless (defined $ENV{APPLEJACK}){
    my $cmd = "env APPLEJACK=TRUEBLUE $^X $0";
    print "Running exec $cmd\n";
    exec($cmd, @ARGV);
    exit 0;
    }else{
        print "APPLEJACK already defined\n";
    }
}

print "STARTING " . $ENV{APPLEJACK} . "\n";
